DOC, I haven't seen that one yet, but do you realize that Danny Divito only had about six weeks(?) available to work on the Sunny in Philadelphia series, so they filmed every scene in which he had a part .... without shooting the rest of that episode in its normal sequence.
Once he left the set for good they shot the rest of 'the story-lines' and built it like a big, moving, jig-saw puzzle or so I've been told by someone who knows this stuff..
Has anyone seen BLUE MOUNTAIN STATE? It's a free watch on IMDB.com unless it's been moved lately. Funny college football fraternity stuff that could never be shown on regular TV and worth a watch.
